POCT detection-fluorescent microsphere labe♥★ling technology

Fluorescent microsphere labeling te★♠±&chnology uses the principle of membrane chrom<↕π&atography double antibody san•¥dwich method to detect influenza A and /π∑©¶ or influenza B virus antigens in sam♥λ♥ples. During the test, the treated&​ samples are added dropwise to >•✘<the sample wells corresponding to thφ÷αe two detection areas ✘♣of the test cards A and B. When the influenza A♦↑  and (or) B viruses are present in the sample,←×₽€ the virus antigen and quantum d↑< ∑ot nanospheres After±‍‍ the labeled influenza$™ A and (or) influenza B virus ©₹©¥nucleoprotein monoclonal antibody I i✘±s combined, when the chromatography lineδ₹≤ is detected, it will bδ∑→e captured by the coated influenza A σ‍™"and (or) influenza B virus nucleoprotein mon↔↑≠oclonal antibody II Gather at the positio®≥n of the detection line to form a fluorescent b"€♦and A line and (or) B line. Under ultravioleδ∏≤♦t irradiation with a wavele★¶ngth of 365nm, it can be determined by tβαhe naked eye that the influenza A an§π​d (or) B virus is po™£ sitive, or by fluorescence The result of the chr‍↓Ω←omatography test strip reader is positi±∏πve for influenza A and / or B viruses.  ε
